There are oh so many, but right now mine would have to be 'File Under: Easy Listening' by Sugar - probably the best thing Bob Mould ever did, released right in time for Britpop to happen and everyone to ignore it. If there is a God, he'll have seen to it that Sony Records didn't take one look at the sales figures and delete it forever when they bought out Creation; but there must be copies still circulating. Buy it, and swoon.

There's a nice little Sugar/Bob Mould biog at http://www.creationrecords.org.uk/sugar.htm
